Note 2: VL must be less than or equal to VCC during normal operation. However, VL can be greater than VCC during startup and
shutdown conditions.
Note 3: All units are 100% production tested at TA = +25NC. Limits over the operating temperature range are guaranteed by design
and not production tested.
Note 4: Connect a 0.47F capacitor between CP1 and CP2.
Note 5: DIVBAT = [IVBAT(VENAB = VENCD = VIL) - IVBAT(VENAB = VENCD= 0V)]. Guaranteed by design and not production tested.
Note 6: VCC = 5.0V, VL = 1.6V to VCC, VBAT = 2.7V to 3.6V, VENAB = VENCD > VIH, RS = 50I, RL = 1MI, CL = 15pF, TA = -40NC to
+85NC, unless otherwise noted. Typical values are at VBAT = 3.6V, VL = 3.0V, and TA = +25NC.
ELECTRICAL CHARACTERISTICS (continued)
(VBAT = 2.3V to 5.5V, VL = 1.6V to 5.5V, CVBAT = 1FF, CVCC = 2.2FF, CVL = 0.1FF, TA = -40NC to +85NC, unless otherwise noted.
Typical values are at VBAT = 3.6V, VL = 3.0V, and TA = +25NC.) (Notes 2, 3, 4)
